济南抹面砂浆作为建筑施工中的常用材料，凭借其独特的性能，在房屋建造中扮演着重要角色，但并非适用于所有结构部位，其应用需结合房屋建造的具体环节和功能需求。在济南气候条件（夏季多雨、冬季寒冷）和建筑风格影响下，抹面砂浆的合理使用既能提升墙体质量，又能增强房屋的耐久性，成为房屋建造中不可或缺的辅助材料。

　　Jinan plastering mortar, as a commonly used material in construction, plays an important role in building construction due to its unique properties. However, it is not suitable for all structural parts, and its application needs to be combined with the specific links and functional requirements of building construction. Under the influence of Jinan's climate conditions (rainy summers and cold winters) and architectural style, the reasonable use of plastering mortar can not only improve the quality of walls, but also enhance the durability of buildings, becoming an indispensable auxiliary material in building construction.

　　抹面砂浆可用于房屋墙体的表面处理，是墙面装饰与防护的基础。在砖石结构或混凝土墙体砌筑完成后，墙面常存在不平整、缝隙等问题，抹面砂浆通过分层涂抹（通常分底层、中层、面层），能填补墙面缺陷，使表面平整光滑，为后续装饰（如涂漆、贴砖）提供良好基底。底层砂浆（厚度 5-10mm）侧重与基层粘结，多采用水泥砂浆，利用水泥的胶凝性与墙体形成牢固结合；中层砂浆（厚度 10-15mm）主要起找平作用，可根据墙面平整度调整厚度；面层砂浆（厚度 3-5mm）则注重表面光洁度，常添加细砂或粉煤灰改善和易性，使墙面细腻平整。济南多风天气下，平整的墙面能减少风荷载对墙体的冲击，同时避免雨水在墙面凹陷处积聚，降低渗漏风险。

　　Mortar can be used for surface treatment of building walls and is the foundation for wall decoration and protection. After the completion of masonry in brick and stone structures or concrete walls, there are often problems such as unevenness and gaps in the wall surface. The plastering mortar can be applied layer by layer (usually divided into bottom layer, middle layer, and surface layer) to fill the wall surface defects, making the surface flat and smooth, and providing a good foundation for subsequent decoration (such as painting and tiling). The bottom mortar (thickness 5-10mm) focuses on bonding with the base layer, often using cement mortar to form a strong bond with the wall using the cementitious properties of cement; The middle layer mortar (thickness 10-15mm) is mainly used for leveling, and the thickness can be adjusted according to the flatness of the wall surface; The surface layer mortar (thickness 3-5mm) focuses on surface smoothness, often adding fine sand or fly ash to improve workability and make the wall surface delicate and smooth. In windy weather in Jinan, a flat wall surface can reduce the impact of wind loads on the wall, while avoiding rainwater accumulation in wall depressions and reducing the risk of leakage.

　　在框架结构房屋中，抹面砂浆是填充墙与框架连接部位的重要处理材料，能增强结构整体性。框架结构的梁柱与填充墙（如加气混凝土砌块、空心砖）之间存在材质差异，受温度变化影响易产生收缩裂缝，抹面砂浆施工时，需在接缝处铺设耐碱玻纤网格布，再涂抹砂浆，利用网格布的抗拉性能抑制裂缝产生。济南冬季寒冷，墙体易因温度变化出现热胀冷缩，抹面砂浆中的柔性添加剂（如可再分散乳胶粉）能提升砂浆的柔韧性（压折比≤3.0），减少因墙体变形导致的砂浆开裂，确保墙面完整性。对于外墙，抹面砂浆还需具备一定的防水性（吸水率≤10%），能阻挡雨水渗透，保护墙体内部结构，尤其适合济南多雨季节的房屋防护。

　　In frame structured houses, plastering mortar is an important material for filling the connection between walls and frames, which can enhance the overall structural integrity. There are material differences between the beams and columns of the frame structure and the infill walls (such as aerated concrete blocks and hollow bricks), which are prone to shrinkage cracks due to temperature changes. When applying mortar, alkali resistant fiberglass mesh cloth should be laid at the joints, and then mortar should be applied to use the tensile properties of the mesh cloth to suppress crack formation. Jinan is cold in winter, and walls are prone to thermal expansion and contraction due to temperature changes. Flexible additives (such as redispersible latex powder) in the plastering mortar can enhance the flexibility of the mortar (compression ratio ≤ 3.0), reduce mortar cracking caused by wall deformation, and ensure the integrity of the wall. For exterior walls, the plastering mortar also needs to have a certain degree of waterproofing (water absorption rate ≤ 10%), which can block rainwater infiltration and protect the internal structure of the wall, especially suitable for building protection during the rainy season in Jinan.

　　抹面砂浆可用于房屋的保温层防护，是保温系统的重要组成部分。济南新建房屋多采用外墙外保温系统，保温层（如聚苯板、岩棉板）外侧需涂抹抹面砂浆，形成防护层，保护保温材料免受外界环境侵蚀。这类抹面砂浆需具备与保温层的良好粘结力（拉伸粘结强度≥0.1MPa），同时有足够的抗冲击性（抗冲击强度≥3J），能抵御外力撞击（如施工碰撞、风吹杂物冲击），避免保温层破损。冬季济南气温较低，抹面砂浆需能承受 - 15℃至 30℃的温度波动，经冻融循环（25 次以上）后无空鼓、剥落，确保保温系统长期有效，减少房屋能耗损失。

　　Plaster mortar can be used for the insulation layer protection of houses and is an important component of the insulation system. Newly built houses in Jinan often use external wall insulation systems. The outer side of the insulation layer (such as polystyrene board and rock wool board) needs to be coated with mortar to form a protective layer, which protects the insulation material from external environmental erosion. This type of plastering mortar needs to have good bonding strength with the insulation layer (tensile bonding strength ≥ 0.1MPa), as well as sufficient impact resistance (impact strength ≥ 3J), able to resist external impact (such as construction collision, wind blown debris impact), and avoid damage to the insulation layer. In winter, the temperature in Jinan is relatively low, and the plastering mortar needs to be able to withstand temperature fluctuations of -15 ℃ to 30 ℃. After freeze-thaw cycles (more than 25 times), there should be no hollowing or peeling, ensuring the long-term effectiveness of the insulation system and reducing energy consumption losses in the house.

　　不过，抹面砂浆不能作为房屋的承重结构材料，无法替代砖、混凝土等主体结构材料。其主要成分是水泥、砂、添加剂等，虽然硬化后有一定强度（抗压强度≥5MPa），但抗拉强度低，无法承受房屋自重及外部荷载，若用于承重部位，会导致结构安全隐患。在济南房屋建造中，抹面砂浆仅能作为辅助材料，用于非承重墙体的表面处理、保温层防护等，而承重墙、梁柱等关键结构部位仍需依靠钢筋混凝土、砖石等承重材料，两者分工不同，共同保障房屋的安全与稳定。

　　However, plastering mortar cannot be used as a load-bearing structural material for houses and cannot replace main structural materials such as bricks and concrete. Its main components are cement, sand, additives, etc. Although it has a certain strength after hardening (compressive strength ≥ 5MPa), its tensile strength is low and cannot withstand the self weight of the building and external loads. If used in load-bearing parts, it can cause structural safety hazards. In the construction of houses in Jinan, plastering mortar can only be used as an auxiliary material for surface treatment of non load bearing walls, insulation layer protection, etc., while key structural parts such as load-bearing walls, beams, and columns still rely on load-bearing materials such as reinforced concrete and bricks. The two have different responsibilities and work together to ensure the safety and stability of the house.

　　济南抹面砂浆的使用需适配本地建筑材料特性，确保施工效果。济南地区常用的墙体材料有加气混凝土砌块、普通黏土砖等，抹面砂浆需根据基层材料调整配方：针对加气混凝土砌块的高吸水性，砂浆需提高保水性（保水率≥88%），避免因失水过快导致空鼓；对于黏土砖墙体，砂浆可适当提高水泥用量，增强粘结强度。施工时需控制环境温度（5-35℃），济南夏季高温时需避开正午施工，防止砂浆失水过快产生裂纹；冬季施工则需采取保温措施，确保砂浆在正温下硬化，避免受冻影响强度发展。

　　The use of Jinan plastering mortar needs to be adapted to the characteristics of local building materials to ensure construction effectiveness. The commonly used wall materials in Jinan area include aerated concrete blocks, ordinary clay bricks, etc. The formula of the plastering mortar needs to be adjusted according to the base material: for the high water absorption of aerated concrete blocks, the mortar needs to improve its water retention (water retention rate ≥ 88%) to avoid hollowing caused by rapid water loss; For clay brick walls, the amount of cement used in mortar can be appropriately increased to enhance the bonding strength. During construction, it is necessary to control the ambient temperature (5-35 ℃), and avoid working at noon during high temperatures in Jinan in summer to prevent the mortar from losing water too quickly and causing cracks; During winter construction, insulation measures should be taken to ensure that the mortar hardens at positive temperatures and to avoid the impact of freezing on strength development.
